Speechify is absolutely brilliant. Growing up with dyslexia this would have made a big difference. I’m so glad to have it today.

Cmu SPphinx reviews

Sphinx is easy to install and setup and performs surprisingly well without any forced grammar. With PocketSphinx you can easily get some results, enabling you to focus more on configuring sphinx for your project at hand. The support is excellent, both in reaction time (on the forums and the IRC channel) and of high quality.

"The program can't start because MSVCR110.dll is missing" Despite the fact I DO have it installed. This program will waste your time as it doesn't work.

The Telegram group is a great idea, but Nikolay doesnt answer right. Not everybody can dedicate their lifes to "speech recognition". EDIT: I was 2 harsh on him. He is trying his best to help people, even tho , he doesnt have to (join the telegram group and see it yourself) . If you want to use CMUSphinx, do it. But it isn´t the easiest. Thank you Nikolay <3

Rev.ai reviews

I was able to save my audio from other system and share it with Rev. The turnaround time to complete the job was super fast and the output was quality.

I like the layout and ease of use. I think the price is fair and the quality is great most of the time.

Quick work delivered with good quality of work by Rev for transcription and foreign subtitles services. The costing also is very attractive.
